MUSIC-LEAF TURNER.

PECIl-ICATION forming part of Letters Patent No. 348,323, dated August31, 1886.

Application filed May 27, 1885.

To @ZZ whom it may concern:

Be it known that I, THOMAS H. GARLAND, of Chicago, in the county of Cookand State of Illinois, have invented a new and Improved MusicLeafTurner, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved music-leafturner, which is so constructed that it can be released at the propertime to turn a page.

The invention consists in the construction and combinations of parts, aswill be fully set forth and described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding` parts in all the figures.

Figure l is a face view of the lower part of my improved music-leafturner. Fig. 2 is a sectional plan view of the same on the line m Fig.l. Fig. 8 is a cross-sectional view of the same. Fig. I is a detail planview of the mechanism for throwing the arms holding the leaves. Fig. isa front view of the same.

The rack A is provided at its bottom with the ledge A', on which thebottom edges of the sheet music I3 rest, which ledge is provided with arecess, C, in thebottom of which a spring-strip, D, is secured, the freeend of which is at the middle of the bottom edge of the rack, and hasalug, D', projecting through a slot, C', in the ledge, and from the topof the ledge a rod, F, projects from the free end of kthe spring overthe rack to the top of said rack. A box, F, is hinged on the under sideot the lower part of the rack. XVithin the said box a spindle or rod, G,is held on clips G', projecting from the underside ofthe rack, and onthe said spindle a spool, II, is mounted to revolve and slide, and ispushed toward the lower end ol'` the spindle by a spiral spring, H',surrounding the spindle between the upper end ofthe spool and the upperclip G.

Between the lower clip G' and collar I on the spindle a series of ilatrings, .I are mounted on the spindle, and each ringis provided with anarm, K, on the outerend of whichaspringclip, Il', or other device forholding the musicleaves at their lower outer corners is secured. Thearms Ii gradually increase in length, the lowest arm being the longest.

Serial No. 167,107. (Modem A half-sleeve, M, is secured to and projectsbeyond the lower part of the spool H, and is provided at its outer orlower end with parallel semieircular flanges N, between which aprong,O',passes, formed on the end of a springstrip, O. secured to thelower surface of the ledge A' at the left-hand end of the same. Astop-lug, I?, is also secured on the half-sleeve M. A cord, Q, issecured to and wound around the spool II, passed through an opening inthe side of the box F, and secured to a spring, R, on the under side ofthe rack.

Cords S and T are secured to the spool H and wound around the same inthe inverse direction of the cord Q, and the end S is passed to the leftside of the rack and suitably guided. The cord T is passed through theback of the box F, and connected with an elbowlever shown in dottedlines in Fig. 3, and conneeted by suitable rods and levers with a pedal.

The rack is provided below the ledge A' with a slot, XV, into which thearms Ii can swing, and that part ot' the rack below the slot isconnected with the part above it by strips V.

Vashers are placed between the rings J, and the rings J are of suchdiameter that the halfsleeve M can pass over them. It will be understoodthat in practice these washers will only be allowed a sliding movementon the spindle G and rotary movement, so that when a swinging arm isturned it cannot by friction on one of said washers cause the adjacentarm to turn. This may be accomplished in any ordinary manner, as, forinstance, by a splineand-groove connection between the spindle andwashers.

The operation is as follows: The sheet-music is placed on the rack andheld in place by the rod or wire E, pressed upon it at the middle by thespring D, the said spring being raised by means of the lug D' to permitpassing the sheet-music under the rod. All the leaves are folded uponthe right-hand side of the rack, and the arms K are swung to the right,and the leaves held by theelips Ii', the uppermost leaf being held bythe shortest and uppermost arm, K. On swinging the arms K to the rightin the manner set forth the spring O is pushed against the bottom of theledge and presses the spool II and its half-sleeve M upward, so that theend of the front flange IOL) vIO

fas

rests against the uppermost arm, K. By .pulling on the cords S or T thespool H and its half-sleeve M are revolved in the direction of the arrowa', Fig. 4, and as the end of the the lower flange, N, rests againstthe, bottom edge of the uppermost arm, K, the said arm is swung in thedirection of the arrow a and to the left, and carries the uppermost leafwith'it from right to left. The springs 'H' and O then force the spool Hand its half -sleeve M downward until the end of the lower flange, N,rests against the bottom edge of the second arm, which is thrown fromright to left in the manner set forth above when the spool is turned,and so on. Every time an arm has been thrown the spool H andhalf-sleeveM are moved downward to bring the edge of the lower flange against thebottom -edge of the next arm K, and so on. The spring R turns the spoolH in the inverse direction of the arrow a after the tension on thc cordsS or Thas been removed. The stop P prevents the spring R from turningthe spool H too farin the inverse direction of the arrow a.

Having thus described my invention, Iclaim as new and desire to secureby Letters Patent-- 1. The combination, with the spindle and a series ofswinging arms carried thereby, of a revoluble spool on said spindle, ahalf-sleeve on said spool for throwing the swinging arms,

a plate-spring pressing the spool toward the swinging arms, the saidspring also bearing on the swinging arm adjacent to it, and means forthrowing and reversing the movement of the spool on the spindle,whereby, when one or more of the swinging arms are Vreversed to turnback one or more pages of music, the said arms will press on the springand cause it to slide the spool on the arm to automatically set saidswinging arms, substantially as described.

2. The combination, with the'rack, the spin- X dle G, the series ofswinging arms K on the lower end of the spindle, the spool H, loosely=mounted on the spindle above the swinging arms, and having thehalf-sleeve M, adapted to engage with its lower edge the swingingv armadjacent thereto, the spring O, secured to the rack, extending acrossand bearing on the upper swinging arm, and connected to the lower partof the half-sleeve to press the spool downward, the cord Q, secured atone end to the spool, and the spring R, connected to the rack and to theother end of cord Q, for reversing the spool, and the throwing-cords ST, substantially as set forth.

3. The combination, with the rack B, provided with the ledge A, slottedat W, of the casing F, hinged to the back of the rack at its lower end,the spindle G within the casing, the swinging arms on said spindleextending through slot W, the spool on the spindle above the swingingarms, the half-sleeve M, adapted to engage said arms and having twoflanges, N, on its lower edge, the spring O, secured to the under sideof the ledge and having an extension resting in the space betweensaidflanges, and bearing between its ends on the upper surface of theswinging arm adjacent to it, and thereby preventing more than one armbeing swung at once, the reversing-sprin g R, and cord Q,and thethrowing-cords connected with the spool, substantially as set forth. 'i

4. The combination, with the rack B and the ledge A, having slots C C,of thc horizontal spring D, having an arm, D','extend ing through theslot C', and the vertical rod E, extending through slot C upward to ornear the top of the rack, substantially as set forth.

5. The combination, with a rack, of the ledge A', the spring D, the lugD', the rod or wire E, a series of swinging arms on a'spindlc,

a sliding and revolving spool on said spindle,

and a flange connected with said spool and acting on the arms,substantially as herein shown and described.

6. The combination, with a rack, of the spindle G, the arms K, the spoolI-I, the halfsleeve M, the stop P on the same, cords for turning thespool, and a spring for turning the spool in the inverse direction ofthat in which it is turned by the cords, substantially as herein shownand described.
